To all whom it moy concern:

lle it known that l, CARL O. HEns'rnoM, a citizen of the United Statesol America, residing at Springfield, in the county oi' Hampden andStateof Massachusetts, have invented new and useful improvements inLubricating Means for Internal Combustion Engines, of which thefollowing is a specification.

This invention relates to improvements in crank cases for internalcombustion engines and has special reference to origines of the doublecylinder` type, the. particular object oi the invention being to'provide means for oiling the interior of the cylinders 'from thefly-wheel of the engine by the splash or centrifugal system, and at thesame time to prevent the wheel lrom throwing the oil only into onecylinder, it being understood that the ly-wheel easingis 'adapted torevolve in oil in the lower part oi the casing. v

Broadly, the invention consists in providing webs or plates [orpartially closing the openings in the crankcase where the enginecylinders are attached so that the ily-wheel is prevented from throwingthe oil into one cylinder only, will be fully described in the body oithe specification.

ln the drawings forming part of this application,"- Figure 1 is asectional plan` view of my improvement on the line l-l, Fig. 2, showingthe plates or webs partially closing the openings in the crank-easing.Fig. 2 is a'vertical sectional view on the line 2-2, of Fig. l, showingthe cylinders and casing in section; also disclosing the arrangement andlocation of thepiston-rods, fly-wheel, and the lubricant in the casing.

Referring to the drawings in detail, a designates the crank-casing inwhich is rotatably mounted the ilywheel b; c and d designate piston-rodsthat are connected to the common crank shaft e. These pistonrods, itwill be noticed, are located between the two parts or sections f and gthat compose the {1y-wheel, as clearly shown in Fig. l..- v A h indidesignate metal webs or plates that partially close the entrance to thelowere'nds el the cylinders j and lc and are preferably cast withtliecasing a. Thesey webs or plates, shown in plan view 'in Fig. i, closeabout one-half oi the arca of each cylinder. The sec tion or portion fol the flywheel, from the plan view ol' lfig. l, can throw oil into thelower end ol the cylinder k, but can `not throw the oil into the lowerend oi -the cylinder j, except a small quantity through the opening wi,and the fly-wheel serztion y can throw the oil into the lower end el thecylinder j but can not into ythe lower end of the cylinder c, except asmall quantity through the opening o i n the plate i. Each section orportion ol the ily-wheel therefore oils.its own cylinder, and all of theoil is not thrown into one cylinder, as

would be the case il the plates h and i were omitted,l

-lower end oi' the casing a, as clearly designated by the letter q.

The plates l1. and i, it will be observed in Fig. l, are

'ormedor cast with the casing a. in the openings where the cylinders jand k are bolted to the easing o.

What I claim, isz-v 1. In an oiling system of the class described, inconnu` nation, a casing, a rotary member mounted therein, a plu ralityof cylinders secured to thc casing.: and having pistons thereinconnected vto the rotary member, the rotary member having two sectionsor portions and located under oplsitely disposed plates or webs thatpartially close the opeljng to the cylinders, whereby the lubricantwhich is contained in the casingr may be equally distributed by thecentrifugal action of tho rotarymember to the cylinders, said platesbeing also provided with diagonally disposed openingsover the rotarymember, as described.

2. In combination with a casing. a rotary member made in two sectionsand located therein,a casing having openings in one side'thereof andprovided` with the oppostely disposed plates partially closing,r saidopenings 1d located over opposite edges of the rotary member, cylinderssecured to the casing and in the openings thereof, whereby durin "themovement of the rotary member the lubricant will e equally distributedtoV the cylinders by the centrifugal action of the rotary members,l saidplates being also provided with oppositely disposed openings, :is deAscribed.

' 3. In an onine-system of the centrifugal type, n. casing forcontaining a lubriczin't in,the lower portion thereof, a

Jrotary member mounted in the casing' in contact with the lubricant, theeasing.; being.: provided with openings nl: one

side thereof and having; plaies located in the openings und partiallyclosing the suine, said plates being,r located over the opposite edgesol` lho rolalry member, hereby the lu
